我最近开始研究 AspectJ 并为 Logging 编写了一个简单的 Aspect。

我在 pom 文件中定义了以下依赖项:

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
        </dependency>

ear/lib 文件夹中存在以下工件:

• aspectjrt-1.7.1.jar
• aspectjweaver-1.7.1.jar
• spring-aspects-3.2.1.RELEASE.jar

我在服务启动时遇到异常。:

Edit 1 - 我正在使用 JBOSS 7.1，我认为 AspejctJ 和 JBOSS 存在一些问题.

最佳答案

maven 项目中像这样的 NoClassDefFoundError 通常来自库冲突。问题中没有足够的信息，您只提供了您的 pom 的片段，并没有显示您正在使用的 spring 方面的版本。您需要运行 mvn dependency:tree 并验证您使用的所有 aspectj 依赖项的版本号一致。

编辑:肯定存在某种库冲突，因为您在问题中提到了 spring-aspects 3.2.1.RELEASE，但堆栈跟踪包含很多对 spring 3.1.1 的引用。发布库。

关于java - 异常 java.lang.NoClassDefFoundError : org/aspectj/lang/annotation/Aspect，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35392851/
